Pentair has now increased the protection level of its Hoffman PROAIR air conditioners NEMA 4 and NEMA 4X to IP66, especially for use in harsh and corrosive environments. In the food and beverage industry, as well as in highly corrosive environments, equipment is exposed to higher requirements. In cooling such facilities, the company says its Hoffman PROAIR air conditioners offer ideal protection.
RectorSeal® Corp. introduced SureSeal® Vent-Guard, a vent stack device for eliminating toxic sewer gas and odor egress and migration to nearby rooftop HVAC system outdoor air intakes. The patent-pending Vent-Guard is available in three sizes designed to fit 2-, 3-, and 4-in-diameter commercial building plumbing vent stacks and restaurant grease interceptor vents.
Technical Systems (TSI), a division of RAE Corporation, has released the new Adiabatic Pre-cooling Evaporative X-change (APEX™) cooling technology. The company reports the APEX combines evaporative cooling technology with the simplicity of air cooling to deliver low-maintenance, highly efficient cooling systems. APEX is ideal for data centers, hospitals, colleges and universities, and more.
GF Piping Systems has introduced the Type 514-519 High Flow Diaphragm Valve Series. The valves are designed to provide a true break-through for weir style valves. The valve features an optimized, turbulence-free flow geometry that offers significantly increased flow rate performance and lower energy consumption, according to the company. These features expand the valve’s suitability for applications where diaphragm valves were previously not considered due to flow restriction.
The Grundfos PACOpaQ® is a fully-integrated and compact HVAC packaged pumping system designed for chilled and hot water distribution, condenser water, geothermal loop, district heating and cooling, and many other water-based systems. The system pairs centrifugal pumps with the intelligence and efficiency of a dedicated HVAC control, which automatically determines the most efficient speed and optimum number of pumps needed to meet desired flow and pressure.
Daikin Applied has expanded its Rebel™ commercial packaged rooftop systems from 3 to 15 tons to include 16- to 28-ton sizes, enabling owners of larger buildings to decrease the number of units required, reducing overall installation costs.
The Filterscan® WiFi Air Filter Monitor and Notification System from CleanAlert issues text/e-mail alerts when an air filter needs servicing –—ideal for operations or property managers responsible for servicing large or multiple facilities.
A new product designed by Nippon PMAC will now allow hotels to deliver room-by-room climate control of a 4-pipe system with no structural alteration to its existing 2-pipe installation. The system, known as PAFMAC, will provide hotel guests with room temperatures suited to their particular tastes.
Spirax Sarco has released the CSM-C 600 compact clean steam generator. This unit is a skid mounted system that is designed to provide dry saturated steam that meets the requirements of HTM2031, HTM2010, and EN285 standards. The CMS-C 600 generator can produce up to a maximum of 1,275 lb/h of clean steam at 45psig — dependent on plant steam pressure and feedwater temperature. The generator can be used across a wide range of industries and in any application that relies on sterilization or humidification as part of its process.
Why was one floor’s laboratory ventilation failing to keep up, when it was even the closest floor to the rooftop fans? Some system sleuthing led two engineers to a fitting conclusion. Read more stories in May Issue 2017.
